Michael T. Riley
Senior Vice President

First Financial Bancorp
300 High Street
P.O. Box 476
Hamilton, OH  45012

Dear Mike:

         You are employed by First Financial Bancorp and First National Bank of
Southwestern Ohio, a wholly owned subsidiary of FFBC, ("FFBC") in a key
executive position. Continuity of the management of FFBC and its affiliate banks
is a critical factor in the continued success of FFBC. The Board of Directors of
FFBC believes it is in the best interest of FFBC to encourage the continued
effort and dedication of key members of management to their assigned duties.

         In consideration of the mutual promises contained in this letter, FFBC
shall provide to you, and you shall receive from FFBC, the benefits set forth in
this letter ("Agreement"), if your employment with FFBC, or its affiliate bank,
is terminated during the term of this Agreement.

         1.       Purpose.
                  -------

                  This Agreement establishes certain basic terms and conditions
         relating to your employment with FFBC, and special arrangements and
         dispute resolution proceedings relating to the termination of your
         employment for any reason other than: (i) your retirement; (ii) your
         becoming totally and permanently disabled under the FFBC long-


   2

         term disability plan or policy; or (iii) your death. This Agreement
         supersedes all prior agreements with FFBC and any of its affiliate
         banks or any predecessor businesses, except the Confidentiality
         Agreement concurrently entered, or previously entered, between you and
         FFBC, and the special severance benefits provided under this Agreement
         are to be provided instead of any other severance arrangements offered
         by FFBC or its affiliate banks. Notwithstanding the foregoing, neither
         your termination of employment nor anything contained in this Agreement
         shall have any affect upon your rights under any tax-qualified "pension
         benefit plan," as such term is defined in the Employee Retirement
         Income Security Act of 1974, as amended ("ERISA"); or under any
         "welfare benefit plan" as defined in ERISA, including by way of
         illustration and not limitation, any medical surgical or
         hospitalization benefit coverage or long-term disability benefit
         coverage; or under any non-qualified deferred compensation arrangement,
         including by way of illustration and not limitation, any stock
         incentive plan or non-qualified pension plan; or under the FFBC
         Performance Incentive Plan for any completed plan year.

         2.       EMPLOYMENT.

                  FFBC agrees that, during the term of this Agreement, you will
         be employed with FFBC, and any other direct or indirect subsidiary or
         affiliate of FFBC to which you may be transferred, in your present
         position or in a position that is comparable to your present position
         in compensation, responsibility and stature and for which you are
         suited by education and background and that:

                           (a) you are, and will continue to be, eligible to 
                  participate in any employee benefit plan of FFBC in 
                  accordance with its terms; and

                           (b) you will be entitled to the same treatment under
                  any generally applicable employment policy or practice as any
                  other member of Executive Management Group whose position in
                  the organization is comparable to yours.

                  Those plans, policies and practices that generally apply to
         other members of the Executive Management Group will be referred to in
         this Agreement as your "Employment Benefits." Your Employment Benefits
         may be modified from time to time after the date hereof without
         violation of this Agreement if the changes apply generally to other
         members of the Executive Management Group.

         3.       TERM OF AGREEMENT.

                  This Agreement shall become effective on the date of this
         Agreement ("Commencement Date") and shall continue in effect through
         the earlier of (i) the fifth anniversary of the


   3

Page 3





         Commencement Date; (ii) the date of your retirement, death or total and
         permanent disability; or (iii) the completion of full payment of all
         benefits promised hereunder. Absent your death, total and permanent
         disability or retirement, this Agreement shall be renewed annually from
         and after the fifth anniversary of the Commencement Date unless written
         notice to the contrary is given by you or by FFBC at least six (6)
         months prior to the expiration of the term, including any extension
         thereof.

         4.       TERMINATION OF EMPLOYMENT.

                  Your employment may be terminated in accordance with any of
         the following paragraphs, but only upon one (1) month's advance written
         notice (which period shall be referred to in this Agreement as the
         "Notice Period"):

                           (a) INVOLUNTARY TERMINATION. FFBC may terminate your
                  employment without cause. In such an event, you shall continue
                  to receive your full salary and Employment Benefits during the
                  Notice Period. The expiration of the Notice Period shall be
                  your "Date of Termination." Upon your Date of Termination, you
                  shall be entitled to those benefits provided under Section 5,
                  provided you give FFBC the release and covenant not to sue
                  described in Section 5.

                           (b) INVOLUNTARY TERMINATION FOR CAUSE. FFBC may
                  terminate your employment for "Cause" with written notice
                  setting forth the Cause for termination. "Cause" means a
                  willful engaging in gross misconduct materially and
                  demonstrably injurious to FFBC. "Willful" means an act or
                  omission in bad faith and without reasonable belief that such
                  act or omission was in, or not opposed to, the best interests
                  of FFBC. The expiration of the Notice Period is your "Date of
                  Termination for Cause." Upon your Date of Termination for
                  Cause, you shall only be entitled to those benefits provided
                  under Section 6.

                           (c) VOLUNTARY TERMINATION. You may voluntarily
                  terminate your employment. In such an event, you shall
                  continue to receive your full salary and Employment Benefits
                  during the Notice period provided you satisfactorily perform
                  your duties during the Notice Period unless relieved of those
                  duties by FFBC. The expiration of the Notice Period is your
                  "Voluntary Date of Termination." Upon your Voluntary Date of
                  Termination, you shall only be entitled to those benefits
                  provided under Section 6.

                           (d) VOLUNTARY TERMINATION FOR GOOD REASON. You may
                  terminate your employment by notice setting forth a Good
                  Reason for termination if the notice is delivered to FFBC
                  within thirty (30) days following the occurrence of any "Good
                  Reason." "Good Reason" means a (i) change in the duties of
                  your position, or the transfer


   4


Michael T. Riley

                  to a new position, in violation of Section 2; (ii) substantial
                  alteration in the nature or status of your responsibilities in
                  violation of Section 2; (iii) reduction in your base salary;
                  (iv) refusal by FFBC, or its successor, to renew the term of
                  this Agreement for any reason, prior to your reaching your
                  normal retirement date under the FFBC Pension Benefit Plan; or
                  (v) changes in your Employment Benefits in violation of
                  Section 2. If you give notice of termination for Good Reason,
                  you shall continue to receive your full base salary and
                  Employment Benefits during the Notice Period as in effect
                  prior to the event that is the Good Reason for termination,
                  subject to the right of FFBC to make any changes to your
                  Employment Benefits permitted in accordance with Section 2.
                  The expiration of the Notice Period is your "Date of
                  Termination." Upon your Date of Termination, you shall be
                  entitled to those benefits provided under Section 5, provided
                  you give FFBC the written release and covenant not to sue
                  described in Section 5.

         5.       SPECIAL SEVERANCE BENEFITS.

                  If your employment with FFBC is involuntarily terminated in
         accordance with Section 4(a) or you voluntarily terminate your
         employment for Good Reason in accordance with Section 4(d) and you
         provide FFBC with a separate, written release and covenant not to sue
         (on a form provided by and satisfactory to FFBC) which releases FFBC
         from all claims arising from your employment and termination of your
         employment, and you do not revoke this release and covenant not to sue,
         then you shall receive the following benefits, less any applicable
         withholding required for federal, state or local taxes:

                           (a) your base salary shall be continued in effect for
                  a period of twenty-four (24) months from your Date of
                  Termination (hereinafter called your "Severance Pay Period");

                           (b) if, prior to your Date of Termination, you have
                  participated in the FFBC Performance Incentive Plan for a
                  complete calendar year, you will receive an incentive
                  compensation payment within thirty (30) days of your Date of
                  Termination in one lump-sum in an amount equal to 2.0 times
                  the percentage of the incentive payment made or required to be
                  made for the calendar year pursuant to the Performance
                  Incentive Plan immediately preceding the calendar year in
                  which your Date of Termination occurs;

                           (c) if your Date of Termination is within twelve (12)
                  months after a Change in Control, you will receive a payment
                  within thirty (30) days of your Date of Termination in one
                  lump-sum in an amount equal to the total of the following:

                           Control under the First Financial Bancorp 1991 Stock
                           Incentive Plan (the "Incentive Plan") that you cannot
                           exercise as a result of your termination of
                           employment, the difference between the fair market
                           value of such Stock, determined as of your Date of

                           such Restricted Stock, determined as of your Date of
                           Termination and as if all restrictions had been
                           removed.

                           be determined after any adjustments made by the
                           Committee under Sections 8.8 and 11.1 of the
                           Incentive Plan, and after any amendments made to the

                           has been approved by the shareholders (or the Board
                           of Directors or appropriate officers if shareholder
                           approval is not required) and consummated; (c)

                           Exchange Act; or (d) individuals who were members of
                           the Board of FFBC immediately prior to a meeting of

                  changes to your Employment Benefits permitted in accordance
                  with Section 2; provided, however, that you shall not:

                  (i)      accumulate vacation pay for periods after your Date

                           sickness or illness first manifesting itself, after
                           your Date of Termination;

                           purposes;

         (e)      you shall qualify for full COBRA health benefit continuation
                  coverage upon the expiration of your Severance Pay Period;

         (f)      you shall be entitled to full executive outplacement
                  assistance with an agency selected by FFBC with the fee paid

                  annual base salary;

         (g)      with respect to the Endorsement Method Split Dollar Plan
                  Agreement (the "Split Dollar Agreement") to which you are a
                  party (and solely for purposes of the Split Dollar Agreement),
                  the duration of your Severance Pay Period shall be considered
                  as if it were active employment for purposes of determining
                  whether you were eligible to receive a retirement benefit
                  under the early retirement provisions of First Financial
                  Bancorp Employees' Pension Plan, as provided in Section VI(B)
                  of the Split Dollar Agreement; and

         (h)      if your Date of Termination is within twelve (12) months after
                  a Change in Control, you will receive a payment (the "Split
                  Dollar Payment") within ninety (90) days of your Date of
                  Termination in one lump-sum equal to the present value of the
                  death benefit you would have received under the Split Dollar
                  Agreement, determined as if you had terminated on your Date of
                  Termination, were then eligible to receive a retirement
                  benefit under the early retirement provisions of First
                  Financial Bancorp Employees' Pension Plan (whether or not this
                  is actually

                  the case), and died at age 75 when the Split Dollar Agreement
                  was still in effect. For purposes of this Section 5, present
                  value will be determined using an annual discount rate of 7%.
                  Notwithstanding the prior two sentences, if you elect to
                  receive an assignment of the policy under Section X of the
                  Split Dollar Agreement, the Split Dollar Payment shall be
                  applied to the cash payment to FFBC required under Section X
                  of the Split Dollar Agreement, and any portion of the Split
                  Dollar Payment in excess of the amount required under Section
                  X shall be paid to you.

         (i)      Notwithstanding any other provision of this Agreement, if the
                  receipt of any payment under Section 5 of this Agreement, in
                  combination with any other payments to you from FFBC or its
                  affiliates, shall, in the opinion of independent tax counsel
                  of recognized standing selected by FFBC, result in the payment
                  by you of any excise tax provided for in Section 280G and
                  Section 4999 of the Internal Revenue Code, then the amount of
                  payments under Section 5 of this Agreement shall be reduced to
                  the extent required, in the opinion of independent tax
                  counsel, to prevent the imposition of such excise tax. The
                  reduction of payments under this Agreement shall be made after
                  any reduction made under Section 11.2 of the First Financial
                  Bancorp 1991 Stock Incentive Plan and you will have the right
                  to select the order in which payments under this Section 5
                  will be reduced.

         The release and covenant not to sue which you agree to provide prior to
         the receipt of special severance benefits under this Section 5 of this
         Agreement shall comply with the requirements of the Older Workers
         Benefit Protection Act and applicable state and federal laws and
         regulations. If you do not provide FFBC with a written release and
         covenant not to sue, any claims concerning this Agreement or otherwise
         arising from your employment with FFBC, or its affiliate banks, shall
         be subject to final and binding arbitration as described in Section 7.

6.       BENEFITS UPON VOLUNTARY TERMINATION OR TERMINATION FOR CAUSE.

         Upon your Date of Termination for Cause in accordance with Section 4(b)
         or your Voluntary Date of Termination in accordance with Section 4(c),
         all special severance benefits under this Agreement will be void. In
         such an event, you shall be eligible for any benefits provided in
         accordance with the plans and practices of FFBC that are applicable to
         employees generally.

7.       ARBITRATION.

         Any dispute under this Agreement, and any claims of wrongful or 
         discriminatory

         termination based on any state or federal statute, tort, public policy,
         contract or promissory estoppel theory, including any dispute as to the
         cause or reason for termination, shall be submitted to final and
         binding arbitration, subject to the National Rules for the Resolution
         of Employment Disputes of the American Arbitration Association,
         effective June 1, 1997, except as hereinafter provided:

         (a)      FFBC shall pay the arbitrator's fee;

         (b)      Each party shall bear the cost of its own attorney's fees.
                  However, if you prevail in a challenge to FFBC's determination
                  as to cause for your termination or if you prevail on any
                  claim that you were discriminated against in violation of any
                  federal law or statute, you shall be reimbursed by FFBC for
                  the filing fee and any reasonable costs or expenses incurred
                  in such a challenge, including reasonable attorney's fees;

         (c)      The arbitration hearing shall be held in Hamilton, Ohio,
                  unless the parties mutually agree to another location;

         (d)      Each party shall exchange documents to be utilized as exhibits
                  in the arbitration hearing and each party shall be limited to
                  two (2) pre-hearing depositions of two (2) hours each, unless
                  the arbitrator orders additional discovery;

         (e)      The arbitrator shall be appointed in accordance with Rule 12
                  of the above-referenced Rules of the American Arbitration
                  Association, except that if, for any reason, an arbitrator
                  cannot be selected by the process described in Rule 12,
                  subparts (i) through (iii), the American Arbitration
                  Association shall submit the names of seven (7) additional
                  arbitrators from its Roster and the parties shall select the
                  arbitrator by alternately striking names with the party
                  requesting arbitration first striking; and

         (f)      Either party shall be entitled to an injunction or other
                  appropriate equitable relief to enforce the arbitration
                  provisions of this Agreement and FFBC shall be entitled to an
                  injunction to prevent any breach, pending arbitration, of the
                  Confidentiality Agreement described below in paragraph 8 or
                  the Covenant Not to Compete described below in paragraph 10.

                  It is the intention of the parties to avoid litigation in any
         court of all claims concerning this Agreement, or otherwise arising
         from your employment with FFBC, or its affiliate bank, and that all
         such claims will be subject to this arbitration agreement. Neither
         party shall commence or pursue any litigation on any claim that is or
         was the subject of arbitration under this Agreement. Each party agrees
         that this agreement to arbitrate and the arbitration award are
         enforceable under and subject to the Federal

         Arbitration Act, 9 U.S.C. Section I, et seq. ("FAA"). If the FAA is 
         held not to apply for any reason and the law of the state in which you
         are employed recognizes the enforceability of this Agreement and the
         arbitration award, then this Agreement and the arbitration award are
         enforceable under the laws of the state in which you are employed. Both
         parties consent that judgment upon the arbitration award may be entered
         in any federal or state court that has jurisdiction. The acceptance of
         any benefit under this Agreement shall be deemed ratification of this
         agreement to arbitrate claims. In the event you breach this Agreement
         by filing a lawsuit, at the time your lawsuit is filed, you will return
         any Special Severance Benefits paid to you and be subject to injunctive
         relief enforcing this Agreement.

8.       CONFIDENTIALITY.

         You will not disclose to any person or use for the benefit of yourself
         or any other person any confidential or proprietary information of FFBC
         without the prior written consent of the Chief Executive Officer of
         FFBC. Upon your termination of employment, you will return to FFBC all
         written or electronically stored memoranda, notes, plans, customer
         lists, records, reports or other documents of any kind or description
         (including all copies in any form whatsoever) relating to the business
         of FFBC and fully comply with any separate confidentiality agreement to
         which you and FFBC are parties.

9.       CONFLICTS OF INTEREST.

         You agree for so long as you are employed by FFBC to avoid dealings and
         situations that would create the potential for a conflict of interest
         with FFBC. In this regard, you agree to comply with the FFBC policy
         regarding conflicts of interest and all applicable state or federal
         regulations concerning conflicts of interest applicable to commercial
         bank or savings bank officers.

10.      COVENANT NOT TO COMPETE.

         During the term of this Agreement, and for a period of six (6) months
         following the termination of your employment for any reason other than
         as set forth in Section 4(b), you agree not to be employed by, serve as
         officer or director of, consultant to or advisor to any business that
         engages either directly or indirectly in commercial banking, savings
         banking or mortgage lending in the geographic area of Ohio, Indiana,
         Michigan or Kentucky or which is reasonably likely to engage in such
         businesses in the same geographic area during the six (6) month period
         following your termination of employment.

         and shall be deemed to have been given when delivered or mailed by
         United States certified mail, return receipt requested, postage
         prepaid, in a properly addressed envelope. Notices to FFBC shall be
         addressed to the Chief Executive Officer.

         except pursuant to a written instrument signed by you and the Chief
         Executive Officer of FFBC. This Agreement is binding upon any successor
         to all or substantially all of the business or assets of FFBC.

13.      VALIDITY; COUNTERPARTS.

         This Agreement shall be governed by and construed under the law of the
         State of Ohio. The validity or unenforceability of any provision hereof

         hereof. This Agreement may be executed in one or more counterparts,
         each of which shall be deemed to be an original but all of which
         together will constitute one and the same instrument.
